1Different from the traditional low temperature stirling engine design, we made this stirling engine with a square base. 2Selected high hardness bearing steel cylinder piston, not worry about the breakage and short life of the glass cylinder piston. 3Using aluminum alloy panel and bottom plate, through engraving and milling by high-speed machining center and anodized treatment, this stirling engine model is also an artwork on your desk. 4Run freely on the top of a cup of hot water, no need to fire a alcohol lamp, safer for children. 5It has a wide range of applications for children's science projects, physical/mechanical learning, teacher demonstration props, birthday gifts for friends, family, children, etc.
